The modern wiring colouring is:
Blue is neutral.
Brown is positive.
Green/yellow stripe is the earth.
The original colours were:
Red is positive.
Black is neutral.
Green is earth.
There are a variety of wire coverings depending on what the conductor is used for. There are also different wire coverings for different temperatures where the conductor will be used. To answer the question the wires in a circuit are covered in insulation.

In electrical wiring, the live or "hot" wire is typically brown or red, the neutral wire is typically blue or black, and the ground wire is yellow or green. So, in this case, the brown wire is likely the hot wire, the blue wire is the neutral wire, and the yellow green wire is the ground wire.
Copper wire will undergo plastic deformation even though it does not break like steel wire.
It is not recommended to boil the plastic off copper wire as this can release harmful fumes into the air. It is safer to use a wire stripper or cutter designed for this purpose to remove the plastic insulation from copper wire.
Plastic being nonconducting, it avoids electrocution when covered around electric wire.

There are a number of reasons: If the wire is electrical then it is covered in plastic as plastic provides insulation, this means that if adjoining wires come into contact the electrical current would not cause a short circuit. Normally electrical wire is cooper as it is a good conductor of electricity and does not oxidize/ rust easily. Secondly wire hangers are covered in plastic to prevent the metal (normally mild steel) from rusting. If they were to rust, it would cause orange/ red stains on your clothes.

Plastic wire is much cheaper than using regular metal wire. Another advantage of using plastic wire is that it is much safer and better for the environment.
It is not 'insoluted wire'. That one in named as ' insulated wire' Usually metallic wire carries the current. Just to avoid electric shock it is to be covered by insulators such as rubber or plastic. Some times we use nickel coating which also serves the purpose of insulation.
Ethernet cable. 8 wires in 4 pairs. The wires are twisted around each other and covered with a plastic tube to help prevent interference. The wires are also each in plastic.
Brown Covered Bridge was created in 1880.
Black Bears are covered in black fur, and brown bears are covered in brown fur.
thermosetting plastic
A: When a wire is drawn some means of depositing plastic covering to the wire is required so for adhering a very small thread is placed along the wire so the plastic can have some means of adhesion to the plastic
Gottlieb Brown Covered Bridge was created in 1881.
